The Laser Materials Processing Lab (LMPL) at the University of Iowa pursues research on the advancement of material processing technology and sciences. There are currently three main research thrusts:

  • development of laser engineering methods for new functional materials;
  • development of novel manufacturing processes (via lasers, ultrasonics, friction stir processes); 
  • modeling and simulations of material processes, microstructures and functional properties. 

The lab is directed by Prof. Hongtao Ding

 


Group News:
  • Haoxuan You and Zach Lowery wins the 1st place Popular Choice Award at the 2019 UI Research Open House. Congratulations!
  • Avik Samanta wins the Best Graduate Poster Award at the 2019 UI Research Open House. Congratulations!
  • Congratulations to Avik Samanta for receiving the 2019 Outstanding Teaching Assistant Award from the University of Iowa. He is a doctoral candidate and has served as a teaching assistant for several courses. He is very dedicated, enthusiastic and enjoys working with the students.
  • We recently published a paper in Optics and Lasers in Engineering for our research in Laser Keyhole Cutting of CFRP. For the first time, a keyhole mode cutting is achieved for CFRP materials using a long-pulse nanosecond laser. A high-quality machined surface can be produced with a limited heat-affected zone and little fiber pull-out. The paper can be read from here.

Opening:

At the University of Iowa, we have an immediate Research Assistantship (RA) opening for a project on wind turbine manufacturing, machining and surface treatment. We are looking for highly motivated students with background in one or more of the following areas: Solid mechanics, materials & mechanical behaviors, computer modeling (FEM, dislocation dynamics, MD, or phase field simulation), materials processing (e.g., machining), wind energy, and laser based manufacturing. PhD students in their first year or MS students who intend to continue PhD are preferred. Interested applicants are welcomed to contact Dr. Ding with a resume and a letter summarizing their research experience and research accomplishments.
